ROBERT AMILTON, or PENSACOLA, FLORIDA.

COTTON CHOPPER AND CULTIVATOR.

Specification of Letters Patent.

Application filed July 2, 1912.

Patented Apr. 22, 1913. Serial No. 707,166.

To all whom it may concern:

Be it known that I, ROBERT HAMILTON, a citizen of the United States,residing at Pensacola, in the county of Escambia and State of Florida,have invented certain new and useful Improvements in Cotton Choppers andCultivators, of which the following is a specification.

This invention relates to combined cotton choppers and cultivators, andhas for its principal object to provide improved means forcontrollingcutting disks carried by the machine; also to provide certainnovel constructions and combinations of other parts as will more fullyappear from the following description and the accompanying drawin s.

Tn the drawings Figure 1 is a plan of the machine. Fig. 2 is a verticalsection thereof on the line 22 of Fig. 1. Fig. 3 is a side elevation.Fig. 4 is a detail elevation illustrating the mounting of one of therear wheels.

The lower or main frame of the machine comprises four longitudinal barsor beams 6, with a connecting cross bar 7 at the front.

This frame is carried on front wheels 8 and rear wheels 9, each wheelbeing a swiveling or caster wheel with a turning standard or post 10.The front wheelposts are mounted to turn in supports or brackets 11, andthe rear wheel posts in brackets 12. The front wheels are steered by thetongue 13 which is pivoted at 14 to the front end of an upper frame 15,and connected to the respective posts by links 16 and lever arms 17, thelatter being fastened on the upper ends of the posts. The rear wheels 10are steered by means of a steering post 18 with a handle 19 at the top,said post carrying, at its lower end, an arm 20 connected by links 21 toarms 22 fastened to the rear wheel posts. The seat 23 is mounted on therear end of the upper central frame 15, in pos1- tion to operate thehandle 19 and tohold the rear wheels in central position I provide aspring latch 24 which is pivoted at 25 to a bracket 26 on the frame. Therear end of this latch is located in convenient position for operationby the foot of the driver, and its front end is bent down as indicatedat 27 to engage in a hole at the middle of a circle iron 28 carried bythe lever 20, and normally the end of the latch will engage in the holeand hold the rear wheels in straight position. When it is desired toturn the rear wheels the latch is lifted and the wheels may then beturned by the post 18.

Members 29 extend across the sides of the main frame 6, and the frontends of two pairs of beams 30 are pivotally connected thereto asindicated at 31. Each of these beams carries cultivator blades or shovelplows 32, and also rods 33 covering fenders 33 if desired, thesecultivator beams and appliances being of known construction, andconnected by spring links 34 to arms 35 projecting from a pair of rockshafts 36, one of which is located at each side of the machine, eachrock shaft being controlled by a lever 37 by means of which the shaft 36may be turned to raise or lower the cultivator beams, and the handlevers are equipped with suitable latches to engage notched segments40'to hold the cultivator beams in adjusted position. The central upperframe 15 is supported by forward and rear arched supports 41, the lowerends of which are rigidly connected to the main frame bar 6, and thelower portions of this forward support 41 constitute the members 29beforementioned.

Three pairs of cutting disks 42 are shown applied to the machine, to outthree rows at each operation. Each disk is mounted on a spindle 43 atthe lower end of a post 44, and these posts are connected by andfastened to a cross bar 45, and the upper ends of the posts work throughholes in the front cross piece 7 of the main frame. 46 is a shaftmounted in bearings on the frame provided with segmental levers 47connected by chains 48 to the cross bar 45, and when the shaft 46 isturned the bar 45 and the disks carried thereby are raised and lowered,whereby said disks can bemade to cut deep or shallow, or may be liftedentirely out of the ground as in turning or traveling. The shaft 46 hasan arm 50 connected by a rod 51 to a bent brace or bar 52 on a lever 53which is fulcrumed on the right hand shaft section 36, and bymanipulation of this lever which is adapted to be adjustably locked on asegment 53 the shaft 46 may be turned to raise or lower the disks.

Means are provided for shifting the two outer pairs of disks toward thecenter pair, and to this end additional holes 7 are pro vided in the bar7, and when it is desired to shift the two outer pairs of disks, thesegments 47 and chains 48 are moved along the shaft 46 and bar 45 toextend through the holes 7 and the two outer pairs of disks are thendisconnected from their positions, as shown in Fig. 3, and moved along,or toward the middle, to work through the next adjacent pairs of holesin the bar 7 The middle pair of disks requires no lateral adjustment.

By the means described the disks may be adjusted to desired positionlaterally, and may also be raised or lowered in the operation of themachine. Also the steering of the front wheels, and of the rear wheelswhen necessary, may be effected by the means described.

I claim:

The combination of a frame comprising lower side portions and an uppercentral portion, a seat mounted at the rear of the central frameportion, caster wheels mounted in the forward and rear portions of thelower side frames, a tongue pivoted to the forward end of the uppercentral frame portion and having connection with the front caster wheelsfor controlling the latter, arms extending forwardly from the rearcaster Wheels, an upright steering post mounted in the central frameportion in front of the seat, and having a handle at its upper end, aforwardly extending arm at the lower end of said steering post, andlinks connecting the said post arm with the said rear caster wheel arms.
